What is a common power source for alarm systems?

A standard power source for alarm systems is typically an electrical outlet combined with a backup battery. This combination ensures that the alarm system remains operational during power outages. The standard 120V outlet provides the primary power source, allowing the system to function normally and maintain its features, such as surveillance, alarm triggers, and communication with monitoring services.

The inclusion of a backup battery is critical as it acts as a fail-safe, ensuring that the alarm system continues to operate even when the main power source is interrupted. This is especially important for security systems that need to function reliably at all times, including during emergencies.

While other power sources, such as solar power or backup generators, can be utilized in certain scenarios, they are not as commonly used in standard alarm systems for residential or commercial use. Furthermore, relying solely on batteries or a generator would not provide the same level of consistent power and reliability as a combination of an electrical outlet with a backup battery.
